I'm a little hesitant to access a share with full root access all the 
time.  Do you consider this safe?

What I've worked out is to mount tillie in my smbmt script with the line:
smbmount //tillie/all  /mnt/tillie
which picks up the $USER.
So if I run the script as $USER=root I'm root, otherwise a user even 
though my $UID=0 when I su to run the script and smbmount.

I wish there was some way to "su" into a share but haven't seen it yet.

Ahh, Salt Lick.  I live close by, off Camp Ben Macoulough Rd about two 
miles from Hwy 290 West so I've been there more times than is good for 
me <g>

Come to town some town and I'll treat you.  I'm in the book.
